Long story short, went here for the free whitening in December 2009 had some fillings done, one on a tooth that I had been to another dentist 6 months earlier and no mention of a filling needed from that dentist. In my opinion, his lack of experience led to fillings that Dr. Philipp did needing to be replaced by another dentist a few weeks later. In addition to that my TMJ flared up from the stress and dental work which led to an injury from the TMJ splint I had to have made by another dentist. Buyer beware!
